Systematics and distribution
Agave garciae-mendozae is common in Mexico in the states of Hidalgo , Queretaro and San Luis Potosí in the Rio Moctezuma Basin. It grows widely scattered on limestone slopes, in dry canyons and in woodland at an altitude of 1,800 to 2,350 m. It is associated with Mammillaria species and numerous succulent species.
The first description by Raquel Galván Villanueva and Luis Hernández-Sandoval was published in 2002.
Agave garciae-mendozae is a member of the Marginatae group . Typical are the open rosettes with the stiff leaves and the horny, toothed leaf edges. The taxonomic status is controversial. Characteristic, different properties (rosette, leaf and flower structure) of the other representatives of the Marginatae group, Agave horrida and Agave kerchovei, were used for the determination. Nevertheless, it is similar to the Marginatae representatives Agave lophantha as well as Agave univittata . There is a need for further research.
